Imaging acoustic obstacles by hypersingular point sources
(2011)Research ReportWe investigate a qualitative method for imaging acoustic obstacles in two and three dimensions by boundary measurements. The imaging scheme makes use of the hypersingular point sources. Rigorous mathematical justification of the imaging method is established, and numerical experiments are presented to illustrate the effectiveness of the proposed imaging scheme.Report -

The Collection Tree Protocol for the Castalia Wireless Sensor Networks Simulator
(2011)Technical ReportThe Collection Tree Protocol (CTP) is a well-know protocol that provides a reliable collection service for wireless sensor networks. In this report, we describe our implementation of CTP for the version 3.0 of the Castalia wireless sensor networks simulator. Besides being a reference for researchers interested in experimenting with CTP in Castalia, this report also provides a throughout description of the mechanisms of CTP. As the structure ...Report -
Anisotropic error bounds of Lagrange interpolation with any order in two and three dimensions
(2011)Research ReportIn this paper, using the Newton’s formula of Lagrange interpolation, we present a new proof of the anisotropic error bounds for Lagrange interpolation of any order on the triangle, rectangle, tetrahedron and cube in a unified way.Report -
ISN OSINT Report 1/2011
(2011)ISN OSINT ReportsThis report provides a brief insight into the prevalent approaches to defining and conceptualizing terrorism. It suggests that despite the ongoing intense public debate and academic discourse on the theoretical framework, some largely uncontested and customary conceptual and practical features of terrorism can be derived from the re-examination of contemporary conflict studies and international law.Report -
